Options
A.phenylketonuria
B.colourblindness
C.sickle cell anaemia
D.blood groups
Solution
Multiple alleles control inheritance of blood groups in human A, B, O blood group system is found in humans where the allele IA for A antigen is codominant with the allele IB for the B antigen.
Both IA and IB are completely dominant to the allele IO
Hierarchy of dominace relationships is symbolized as (IA = IB) > IO
Both IA and IB are completely dominant to the allele IO
